My brother got this jacket for me in fall 2009, I have worn it absolutely every season, and every time I go out without it, I wish I had it. It is coffee-stained, a little wrinkled, well-loved, and still my go-to for winter weather. I'll admit, I have tried on warmer jackets, but I've never NEEDED anything warmer than this; throw a waterproof shell overtop in extreme conditions and you're set for whatever might come. It moves well, it packs well, it does it's job, and I've only lost maybe a tiny handful of stuffing in 4 years.
The hood might be my favorite extreme -cold feature, fitting over a helmet, hugging my face comfortably and being easy to adjust.
This isn't an extremely durable piece (see: lightweight), but it's held up to a few intense bush-wacking sessions, a few solid ski runs through forested terrain, and been squashed and snagged on 4 years-worth of gear ranging from casual hiker to vertical mountaineering.
When this jacket finally gives in to all the crap I've put it through, I'll probably be shopping for the same one!
